Problems porting application from NRF52DK board to custom board

[Ed Ang]

I am trying to port an application that works on the NRF52 DK board to a custom board containing a 52832 QFAA chipset. The MCU is connected via SPI to an IMU BMI160 and a SD card slot. In debug mode, the program downloaded successfully to the custom board through the SWD interface. However, stepping through the code, it hangs on the following line.

int8_t ret = nrf_drv_spi_transfer(&spi_BMI160, m_buf, 1, read_temp, payload_size+1);

I have not defined a custom_board header as I am not changing the pin configuration. I defined custom GPIO pins as the SPI interface, as follows.

#define IS_CS_PIN 23
#define IS_MISO_PIN 24
#define IS_MOSI_PIN 17
#define IS_SCK_PIN 13

May I know what I might have missed during the porting process, generating such an error?

Hi Ed

Sorry, but do you mean that your application fails on all these lines? Does this happen at random or what do you mean that they fail at the following lines? This initialization works fine on a DK, correct?

Best regards,

Simon

Hi Simon,

Yes, the place where it hangs is in line 23 - the program downstream of line 23 do not execute. The other lines are positioned down the stack trace.

The problem is consistent and reproducible.

Yes, the program works on the DK.

Thanks,

Ed
